I use an outside firm to prepare my VAT taxes. When I prepare my QBO VAT tax return, I enter tax adjustments, but they hit my bank cash account. How to avoid that?

My goal is to just make the QBO VAT return numbers match what my accountant gives me, so I started using the tax adjustment field when I hit "Prepare Return" to plug a number so the total matches what I actually paid. I have always been selecting my actual bank account as the account of the adjustment and recently noticed that the Tax Adjustment items affected the bank balance I see on the Banking tab. How to amend the VAT return numbers in a way that it doesn't affect my cash? What would be a better account to put the adjustments under? Finally, I realized that it's really hard to reopen and amend old filed returns (I did that for one over the QBO chat and it took a while), so what's the best way to correct the previous adjustments? Journal entries to another non-bank account? Thanks everyone!
